i seem to get all the weird jobs, this one involves 3 extractors fitted in line above a 2.7 mtr cooking range,
each extractor has a 150mm outlet i was thinking of running all 3 into one creating a kind of manifold then from that reduce to 100mm out through the wall using a "fit from inside" vent, as this building has no outside access at rear of building, now question being, do i run it in rigid 100mm round, 100mm flexi, or 100mm flat bearing in mind the run from each hood...
